Retention of Canadian Citizenship

In order to retain Canadian citizenship, some citizens born outside Canada to a parent who was a Canadian at the time of their birth are required to make an application and meet certain requirements before turning 28 years of age. This is called retention of Canadian citizenship.

Retention applies to natural-born children of Canadian citizens, not adopted children, and it applies only to Canadians born outside Canada after February 14, 1977, to a Canadian parent who was also born outside Canada to a Canadian parent. Section 8 of the Citizenship Act says that this second generation born outside Canada will lose their Canadian citizenship at age 28 unless they take steps to retain it.
